JOHN R. FERGUSON, or ABBOTT, TEXAS.

To aZZ whom it may concern:

Be it known that I, JOHN R. FERGUSON, citizen of the United States, residing at Abbott, in the county of Hill and State of Texas, have invented certain new and useful Improvements in Hobbles, of which the following is a specification.

This invention relates to hobblesi for cultivators and other implements.

The aim of the invention is to produce a simple hobble with a few number of parts whereby the cost of manufacture is low and the operation and adjustment is easy.

In carrying out the invention two main elements are provided and these owing to their particular formation and association constitute the hobble. One of the elements takes the form of an upright lever having means at its lower ends'for attachment to one of the beams of a cultivator; while the other element at once provides a segment by which the lever may be locked in adjusted positions, a fulcrum arm to which the,

lever is pivoted, and a connecting. arm extending across to and having hinged con nection with the other cultivator beam. The last element comprises in a single integral piece, the segment, the fulcrum arm, and

the major portion of the connecting arm. The bending of the piece or barwhereby the end of the fulcrum arm forms the center for the arc of the segment, is the main point of novelty.

The invention will be more readily understood from aperusal of the following specification and by reference to the accompanying drawings, wherein:

Figure l is an elevation of thehobbleconnected to a pair of cultivator beams,

Fig. 2 is a plane view of the same, and

Fig. 3 is a detail of the handle of the lever and locking plunger.

In the drawings the numeral 1 designates a lever which has its lowerend offset in the form of an ogee curve as indicated at 2. An adjusting member 3 comprises an arcuate portion 4 which also forms a locking segment through the agency of notches 5 along its upper edge. At one end of the portion 4 the member is bent sharply and returned to form an underlying fulcrum arm 6;

while from the other end of said portion a,

connecting arm 7 extends tangentially.

Specification of Letters Patent. 2 I Patented Oct, 30, Application filed January 10, 1917. "Seria1No. 141,5 24.

The I lever is HOBBLE.

The lever 1 just above its portion 2 is pivoted at 8 to the end of the fulcrum arm and the center of this pivot is coincident with the center of the arc of the portion 4. provided with an ordinary spring pressed locking plunger 9 which engages the notches 5. A pin mounted on the outer end portion of the portion 4 pro jects into the path of the lever and limits its swing in that direction; while the arm 7 limits the swing in the opposite direction.

The lower extremity of the lever is pivoted to a split collar 11 which is clamped around one of the beams 12 of the cultivator, A similar collar 13 isclamped about the other beam. v t

The free end of the connecting arm 7 is SAT 1 T T omen;

provided with a plurality of spaced apertures 1 1 and a link 15 pivoted to the collar 13 is provided with a pluralityof correspondingly spaced apertures 16. The link isoverlapped on the arm so as to register a pair of apertures of each. Bolts arepassed through the pair of registered apertures. and fastened. By this means the connection between the beams maybe lengthened or shortened.

The operation of the hobble needs little explanation as it is quite obvious that by swinging the lever 1 to the right the left hand beam will bedrawn toward the right hand beam and the beams will be spread when the lever is swung to the left.

What I claim, is:

' The combination in a cultivator hobble of an integral upright hand lever having its lower end off-set laterally and carrying a locking plunger, a beam collar, the lower extremity of the lever being pivoted directly to the collar, an arch bar having an integral end bent into a-segment with an under-lying fulcrum arm, said arm having pivoted connection with the lever just above the off-set end thereof and at a pointconcentric with theouter periphery of the segment of the bar, said segment having notches receiving the plunger of the hand lever, and a second beam collar pivotally connected with the arch bar.

In testimony whereof I affix mysignature.

JOHN RQFERGUSON.
